Abstract

Gas Oil fraction of petroleum was hydrotreated (hydrodesulfurization, HDS) over
NiMo/Al2O3 catalyst in a 100 ml autoclave reactor. The reaction was conducted at
340 oC under 5MPa H2 pressure for 60 min. to investigate the correlation of
nitrogen species in the HDS. The inhibition effects of these species are also
investigated by using original and its N-free gas oil. Hydrogen renewal between
stages was attempted to reveal an additional effect of the by-products such as
H2S. All species in the gas oils were analyzed by GC-AED before and after
hydrotreatment. HDS over NiMo/Al2O3 was largely improved by removal of
nitrogen species. Refractory sulfur species were effectively removed by the
removal of nitrogen species and renewal of hydrogen in staged HDS, showing
synergy effects due to simultaneous removal of two inhibitors.
